Question:
We have a 2022 Grand Design Momentum 349M with 8k axles and factory disc brakes. Do you have a package for just the disc pads and rotors? The kodiak package shows calipers which are not really needed. Thanks

There unfortunately isn't a package for just the rotors and brake pads together so you would need to purchase the rotors and pads separately in order to avoid paying for new calipers as well. To find the correct rotors we'll need a bit of information first. We'll need to know your current stud size and the bearing/seal item numbers if you have an hub with an integrated rotor.
If you remove the hub/rotor you can take a look at the outer bearing and the grease seal to see if the item number stamped into them is still legible. For the inner bearing you'll have to remove the grease seal to get a good look. If you don't want your trailer to be down while you wait for a new grease seal to show up then you can also measure the spindle with a digital caliper # PTW80157 at points B, C, and D on the diagram below to get the inner diameter of each part. For the studs you'll just need to check the diameter. It will either be 5/8" or 9/16". Let me know what you find and I'd be happy to look for the correct replacement.
For the brake pads you can use the Dexter Semi-Metallic Disc Brake Pads - 6,000lbs to 8,000lbs # K71-629.
